A display apparatus includes: a first electrode; a bank layer defining a first opening which overlaps the first electrode in a plan view; an emission layer which overlaps the first electrode through the first opening; a second electrode on the emission layer; an encapsulation layer on the second electrode; a first insulating layer on the encapsulation layer, where the first insulating layer includes a first portion overlapping the first opening and defines a trench surrounding the first portion; a touch electrode on the first insulating layer; a second insulating layer on the touch electrode and defining a second opening which overlaps the first opening; and a third insulating layer on the second insulating layer.

Display apparatus

An organic light emitting display device includes: a display panel configured to display an image on a first surface of the display panel, and including: a first display area including a first sub-pixel area, and having a first resolution; and a second display area including a second sub-pixel area and a first transmission area, and having a second resolution that is lower than the first resolution; and a first optical sensor on a second surface of the display panel opposite to the first surface to overlap with the second display area. Accordingly, an image may be displayed at a portion where the first optical module is disposed.

Organic light emitting display device

A display apparatus includes a substrate including a display area and a peripheral area adjacent to the display area, and including a bending area where at least a portion of the peripheral area is bent, a display element on the display area, a pad portion arranged on the peripheral area with the bending area between the display element and the pad portion, an input sensing layer over the display element, and an optical functional layer over the input sensing layer and including a first layer having an opening corresponding to the display element, and a second layer having a different refractive index from the first layer, and the second layer is arranged to extend to the peripheral area and cover the bending area.

Provided is a display apparatus having improved reliability by effectively controlling spreading of an organic layer. The display apparatus includes a substrate including a display area, and a peripheral area outside the display area, a display element at the display area, an input-sensing layer over the display element, and an optical functional layer on the input-sensing layer, and including a first layer, which corresponds to the display area and the peripheral area, and a second layer on the first layer, and having a greater refractive index than the first layer, wherein the first layer defines a first valley portion defining first holes that is on the peripheral area, and that surrounds the second layer.

Display apparatus including multi-layered optical function layer

A display device includes a display layer including an active area including a plurality of pixel areas, and a peripheral area adjacent to the active area, an insulating layer disposed on the display layer, the insulating layer including at least one first opening overlapping the plurality of pixel areas, and at least one second opening in the peripheral area, a refractive index layer disposed on the insulating layer, having a refractive index greater than a refractive index of the insulating layer, and spaced apart from the at least one second opening, and a polarizing layer overlapping the refractive index layer. At least a portion of the polarizing layer overlaps the at least one second opening.

Display device

A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a display element arranged on the substrate in the display area, an encapsulation layer arranged on the display element, a first insulating layer arranged on the encapsulation layer and including a first opening that corresponds to a light-emitting area of the display element, and a second insulating layer covering the first insulating layer. A second refractive index of the second insulating layer is greater than a first refractive index of the first insulating layer, and a side surface of the first insulating layer defining the first opening includes a staircase-shaped step.
